Researchers at Northwestern University uncovered a link between the amount of time spent on a smartphone and depression. The study also found GPS tracking helped identify people with depressive symptoms with an astonishing 87% rate of accuracy. People suffering from depression spend 68 minutes per day on their smartphones, whereas people who are not depressed spend an average of 17 minutes per day on their smartphones. The GPS component of the research led to the discovery that depressed people spend far more time and home, and have very irregular schedules.
